Background

I’m a dedicated and compassionate Registered Dietitian Nutritionist with a Bachelor of Science in Nutritional Science and a strong foundation in acute clinical care. I’ve served as a clinical dietitian at Northridge Hospital Medical Center and currently work at Henry Mayo Newhall Hospital, where I continue to deepen my expertise in evidence-based medical nutrition therapy.

With years of hospital experience, I’ve seen firsthand how nutrition can be a powerful tool for healing, prevention, and long-term wellness. Now, I’m excited to bring that experience into my own private practice—offering personalized, empathetic guidance to help individuals make sustainable changes that improve their health and quality of life.

My mission is to inspire lasting change by empowering and educating clients to build better habits, find balance, and take ownership of their wellness journey. 

Outside of work, I enjoy cooking, traveling, gardening, and spending time with my family which helps me stay grounded and connected to the joy of everyday life.

Jane completely changed how I think about food. She’s patient, knowledgeable, and explains things in a way that actually makes sense.
